my 97 when it hits 5500rpm instead of going into vtec it sounds like it hits a rev limiter and the rpms wont go any higher. This is all done at normal operating temperature and all fluids are fine, the only other problem is the speedo and mileage doesn't work. Could the broken speedo affect the vtec?
Is it the speedometer (the cluster) or the VSS? even if the cluster isn't working VTEC should still engage. How high is your oil? whats your oil pressure in the head like?

the OBD2 scanner says it is the VSS, does any one know where i can get the VSS cheaper then the dealership?
I got my VSS replacement from AutoZone almost 2 years ago. Installation took minutes, fit was great, still works to this day. When my VSS was out, my speedo and Odometer also did not work, which led to a CEL and also no VTEC. Replace the VSS and you'll be back to running fine.

1. Your oil level is low.
2. your vtec screen is full of sludge.
Check your oil level. If its fine unscrew the 3 bolts holding the vtec screen on. Spray carb cleaner in there and watch the gunk fly out. Put it back on and should be like new.
edit: noticed you said u already checked fluids. just try cleaning screen.
It is the VSS because my speedo and odometer doesn't work.
Props to you. Nice find. 90% of the time people come into my work that dont do there regular maintenance and it ends up being a clogged screen. You cant really tell until you actually look at the vehicle.

I could tell what the problem was without looking at his car. He stated in the OP that his speedo and odometer didn't work which, in turn, cause a CEL and when the car can't detect a speed, VTEC will not kick in and the ECU automatically will limit your RPMs as to not cause any kind of damage.
Nice Captain Obvious. If you read the topic it has already been resolved.
